LGU1E223MELB

The LGU1E223MELB is an aluminum electrolytic capacitor in Nichicon's LGU series featuring a snap‑in terminal style and high capacitance in a compact can. It provides 22,000 µF at 25 V with a rated operating range of −40°C to 105°C and is offered in tray packing for production volumes.

Designed for general‑purpose applications, this part combines high ripple current capability and long endurance (3,000 hours at 105°C) to support power assemblies that require bulk energy storage and robust thermal performance.

Key Features

• High Capacitance: 22,000 µF (22 mF) nominal capacitance for bulk energy storage and smoothing in general‑purpose designs.
• Rated Voltage: 25 V DC rated voltage to match mid‑voltage power rails and assemblies.
• Snap‑In Mounting: Snap‑in terminal type with radial can package for secure chassis or board mounting in vertical power assemblies.
• Elevated Temperature Endurance: Specified for 3,000 hours at 105°C under DC bias plus rated ripple current, supporting long‑term operation at high ambient temperatures.
• Ripple Current Handling: Low‑frequency ripple current 4.24 A (120 Hz) and high‑frequency ripple current 4.876 A (50 kHz), enabling use in applications with substantial AC ripple.
• Leakage and Dissipation: Leakage current listed at 2,220 µA; tangent of loss angle (tan δ) of 0.4 measured at 20°C, 120 Hz.
• Operating Temperature Range: −40°C to +105°C to accommodate a wide range of ambient conditions.
• Physical Size and Packaging: Can size φ30×45L with dimensions D: 3.0 cm × L: 4.5 cm; supplied in tray packing and currently in mass production.
• RoHS Compliant: Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Electronics — Provides bulk capacitance and smoothing where 22,000 µF at 25 V is required, benefiting assemblies labeled for general‑purpose use.
• Chassis‑Mounted Power Modules — Snap‑in terminal and radial can package simplify mechanical integration into vertical power assemblies and modular power enclosures.
• High‑Ripple Environments — Suitable for designs that must handle significant AC ripple given its specified low‑ and high‑frequency ripple current ratings and 3,000‑hour endurance at 105°C.

Unique Advantages

• High Bulk Capacitance in a Compact Can: 22,000 µF available in a φ30×45L form factor reduces the number of parallel parts needed for equivalent storage.
• Long Endurance at Elevated Temperature: Rated 3,000 hours at 105°C under ripple and DC bias, offering predictable lifetime performance in hot operating environments.
• Dual‑Frequency Ripple Capability: Published ripple currents at 120 Hz and 50 kHz provide clear design margins for both low‑ and high‑frequency ripple conditions.
• Robust Electrical Characteristics: Defined tan δ (0.4 at 20°C, 120 Hz), leakage current (2,220 µA), and ±20% capacitance tolerance enable precise electrical planning and margining.
• Production‑Ready Packaging: Tray packing and mass‑production status support volume procurement and assemblyLine integration.
